Likely this can only be achieved by writing a custom handler for slapo-sock.

I know LDAP is a data container, and not a

fancy string generator, but I see no other way around this.

An example : my directory contain an inetOrgPerson (say John Doe) with 3 telephoneNumber attributes, say 101010, 202020 and 303030.

I access this directory with 2 clients : the first client displays the data in the right fashion: cn: John Doe telephoneNumber:101010 telephoneNumber:202020 telephoneNumber:303030

But the second client displays only one telephoneNumber attribute, so it displays: cn: John Doe telephoneNumber:101010

Welcome to the wonderful world of multi-valued attributes.

My advice: Don't use them if your clients does not support them nicely.

Given the fact that I have no way to modify the client's source code, how could I do to display all 3 phone numbers ? An idea would be to use rwm with back-relay and do some server side string generation, in order for the second client to retrieve : cn: John Doe telephoneNumber:101010/202020/303030

is there a way to do this ?

This is a very poor solution to the problem.

Ciao, Michael.

hi Pierangelo

Thanks for the answer. Yes that's what I did, I have access to the code of the first client (the one that can handle multi-valued attributes) so I put the phone numbers in a custom attribute "myphone"

cn: John Doe myphone:101010 myphone :202020 myphone:303030

As for the second client (which is Thunderbird), he pulls a single value of the standard attribute "telephoneNumber" which contains the concatenated phone numbers

cn: John Doe telephoneNumber:101010/202020/303030

It may be a poor solution, but at least all my phone numbers are displayed in Thunderbird

I was just curious to see if there was a solution to avoid maintaining the same informations (the phone numbers) twice in the directory, for example by building a "virtual" telephoneNumber attribute on the fly at each request. According to Michael Ströder, this could be done using slapo-sock. I never used it, I'll have a look into it as soon as I can...

The "right" way to do that is to do it at provisioning level, i.e. the application that populates telephoneNumber should also populate a different, custom attribute that contains 101010/202020/303030. Then the problem is: would a dumb client be configurable in such a manner that it can be instructed to show the custom attribute instead of telephoneNumber?
